Location: China, Vietnam
The Tonkin Black Crested Gibbon lives in subtropical and montane evergreen, semi-evergreen and deciduous forest (Jiang et al. 2006, Fan et al. 2009a) and in China it is restricted to broad-leaved evergreen forests (Fan et al. 2009a).
The species is listed as Critically Endangered based on a suspected population reduction of over 80% in the last 45 years (three generations) and a suspected continuing reduction at the same rate for at least 15 years (one generation) in the future, due primarily to widespread hunting and habitat loss.
The Tonkin Black-Crested Gibbon lives in #China and #Vietnam it’s critically endangered on @ICUNredlist due to hunting and #palmoil deforestation. Boycott the brands fuelling their demise #Boycott4WildlifeTweet
In Vietnam, depending on the locality, these gibbons are threatened by mostly human impact on habitat and hunting pressure but it is ultimately always a combination of the two.
These gibbons belong to genus Nomascus. They are known to communicate in species-specific song when defining territory or attracting mates. They sing in regional accents to each other. Males and females have different coloured fur.
